Scope

This Technical Specification includes two methods for the determination of free and released formaldehyde in leathers. One method (Section 5) is relatively simple with regard to the laboratory equipment (colourimetric method), while the other (Section 4) needs more sophisticated equipment (HPLC method). The second method is selective and not sensitive to coloured extracts. The formaldehyde content is taken to be the quantity of formaldehyde contained in a water extract from the leather. The two analytical methods should give similar trends but not necessarily the same absolute result.
